1The differences they discovered in left-handed DNA

The differences they discovered in left-handed DNA (and how they change the structure of their brains)
James Gallagher Health and Science Correspondent, BBC News 5 September 2019

About one in ten people is left-handed, and throughout history there have been many theories as to why this is.
But now, for the first time, a team of scientists from the University of Oxford (England) found the genetic instructions in human DNA that are related to being left-handed.
These instructions, linked to the organization of the internal skeleton of cells, also seem to be highly involved in the structure and function of the brain, particularly in areas related to language.
The researchers published their results in the journal Brain this Thursday, where they suggest that left-handed people may have better verbal skills.
But there are still many mysteries to solve around the connection between brain development and the dominant side.
